An added value can be achieved by combining an existing system with functionalities providing information about the ship's performance in a seaway and an optimum routing algorithm. This paper describes functionalities for predicting slamming, green water on deck, synchronous and parametric roll and the implementation in an existing system to support safe and efficient ocean passage planning. A full scale test on board a container ship crossing the North Atlantic Ocean has been carried out in order to gain operational experience for evaluation of the concept. Further testing is required for validation purposes. %@ 2083-6473
